Hmm...I did the SMC reboot thing about 4 times without any positive results. I guess the problem was that I wasn't plugged in. D'oh!
If you do the Ctrl+Opt+Shift+Power button thing, make sure you're plugged in. Your MagSafe light should turn green for a few seconds. I don't recall anyone mentioning that the notebook had to be connected to an outlet. Perhaps those that aren't getting results from this procedure did the same as me.
When I launched, it almost seems like I'm getting MORE battery life out of Lion than I ever did with SL. Then again...I have to go through a whole cycle before I see if that's really true.
Well, I just got my battery charged to full, and I've been running an iTunes radio station while on battery for the morning. From 100%, it appears that the SMC thing DID solve my issue. (Again, I attempted to SMC without being plugged in 3 times with no results. While plugged in, I did a SMC and I have of course noticed a change.) After two hours of streaming radio, I've dropped to 80% battery, which truly seems like my battery issue is solved.
I've also removed all traces of Flash Player. I'm convinced that has conntributed to solving the issue as well.
I suspect that your removal of Flash Player is benefiting your battery life more than anything else.
An alternative to removing Flash Player is to install ClickToFlash, a Safari extension which allows you to turn Flash Player off but preserves your ability to turn it back on when you need it.
Go to the Safari menu, then Extensions... search for it, install it, you're good to go.
K first of all, I did google this but not intensly before I did this but when I did the shift ctrl opt power thing it didn't boot up right away, then when I finally got into my computer it was making a pop sound like the end of a record, and I was unable to click the option for the batter to show up in the toolbar. once I was able to do so, it said that I had no battery in the toolbar. Since I recently bought a battery and the Power category in system profiler is "normal" do you think it could be the power supply??
oh btw, I was supposed to physically take the battery out and then hold the power button for ten seconds instead of the keyboard command because mine is the first and last unibody with a battery/hdd door/removal panel. This fixed the issue with the batter not being able to connect which I suspect was happening making the sound click and pop.... any experts care to tell me whats up so I can be prepared to talk to the "genius" at apple in an hour and a half??
I think it's my power cord.. but I don't know why that couldn't eventually charge my battery even if it's faulty.
Like some of you I had also tried resetting the SMC and also recalibrating the battery with no good results.
In Snow Leopard I used to get around 6-7 hours of battery life with light average use; after installing Lion, however, my battery only lasted for around 3-4 hours.
After checking out everybody’s responses I realised I had unsuccesfully performed the SMC resetting because my MacBook Pro (Mid 2010) wasn’t connected to the power outlet. I tried again and now it’s back to having the usual 6-7 hours left with a fully charged battery.
I Was Doing The SMC Reset, But Turns Out Older Models Have A Different Procedure:
Reset the SMC of a MacBook or MacBook Pro’s with detachable batteries:
* Shutdown the MacBook/Pro and remove the battery
* Disconnect the power adapter, hold the Power Key for 10 seconds
* Release the power key and reconnect your battery and power adapter
* Turn your Mac on
* Let boot as usual.
Reset SMC of a MacBook or MacBook Pro’s with an internal battery:
* Shutdown your MacBook/Pro
* Connect the power adapter to your Mac
* On the MacBook/Pro’s keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
* Release all keys and the power button at the same time
* Boot your Mac as usual
Reset SMC of an iMac, Mac Pro, Mac Mini:
* Shut down your Mac
* Disconnect the power cord
* Press and hold the Mac’s power button for 5 seconds
* Release the button
* Reattach the power cables and boot the Mac as usual
Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.
I Now Got Back An Acceptable 5:09 Hours Back, I'm Good With That.
Hope This Helps
I tried all those things above but nothing worked for me.
Then browsing into this forum I found the right answer, or at least the one that worked for me. Basically there seems to be a Citrix process that drains my battery life and heats my 2011 MacBook Pro up. So what you have to do to fix this problem is to execute the following command.
sudo launchctl unload -w /Library/LaunchDaemons/com.citrix.agadminservice.plist
Worked inmediately for me shutting the fan up and cooling the Mac instantly, then I checked my battery life and it was restored to the usual levels: 8:00 hours circa.
